- a stacker on a card that is transverse to the working direction running conveyor belt zigzag-like in several pile layers to cross-layer fleece removed and then needled.
- flat structures are produced, which as wall and / or floor coverings are usable.
- To the fleeces a higher strength and thus a It is known to impart greater wear resistance to the first Operation obtained nonwoven fabric in a second operation by needling solidify mechanically.
- the aerodynamic process for the production of nonwovens enables the Manufacture of coarse needled nonwovens.
- the an infeed unit mechanically pre-dissolved, evenly fed Fibers caught by a strong air flow and against a for example perforated rotating drum or a belt.
- the air will sucked through the inside of the drum.
- the fibers form on the drum tangled fleece, which is transported by a carrier.
- This fleece is not like the mechanical process in several Layers plotted.
- the nonwoven fabric produced in this way does not have a high one either Firmness and is usually used only for purposes at who are not concerned with high wear resistance, e.g. in Upholstery etc.
- DE 39 04 526 A1 describes a nonwoven fabric and a method for Manufacture of a nonwoven fabric known, which has a layered structure having.
- the nonwoven fabric has a top layer made of textured on the top Needle fleece, as well as a bottom layer made of needle fleece.
- the lower class is needled against the upper class.
- the relief structure of the upper layer becomes the lower layer with the upper layer not destroyed.
- Prerequisite for the production of such a nonwoven is that the top layer and the bottom layer are present as a needle punch.
- EP 0 013 428 B1 is a flat structure which has a wear layer and has a backing layer made of a nonwoven.
- the Wear layer contains fiber structures made of spherically entangled fibers are connected to the carrier layer by means of needling fibers.
- This Fiber structures are referred to in EP 0 013 428 B1 as ball yarns. Due to the free-flowing and rolling ability of the ball yarns, the ball yarns can be distributed on the wear layer. With a dosed storage a variety of ball yarns in a desired predetermined arrangement of ball yarns, patterns can also be placed on the wear layer become.
- a flat structure is known from EP 0 053 700 A1, which has a wear layer and a carrier layer made of a nonwoven fabric.
- the wear layer is formed by relatively thick strands, the Strands run essentially parallel to each other, so that the flat Formation achieved the impression of a hand-woven flooring.
- EP 0 013 428 B1 and EP 0 053 700 A1 disclose an area Formation in which the wear layer consists of geometric elements with a uniform shape is formed. These geometrically uniform elements can be of different colors, but this will make the uniform surface structure only changed in color.
- the present invention is based on the object specify a method for producing a flat structure by which a flat structure can be produced, which is an optically inconsistent Has surface, the wear layer is rapportok. Another one The aim is to specify a flat structure that is optically inconsistent Has surface of a wear layer, the wear layer being rapport-free. Another object of the invention is a plant for producing a to specify flat structure, by which a flat structure, in particular a nonwoven with a repeat-free, optically inconsistent wear layer is easy and inexpensive to manufacture.
- the method according to the invention for producing a flat structure, in particular a nonwoven fabric, which has a wear layer and a backing layer is formed from a nonwoven fabric is characterized in that at least some of the elements are geometrical in terms of their shape distinguishing, which at least partially form the wear layer, in one Application device are introduced.
- elements with themselves geometrically differentiating form are understood to mean elements that are different Have spatial shape. This can be cylindrical, cuboid or act differently.
- the geometrically different ones Elements are leveled in the application device so that there is an essentially uniform distribution of the elements.
- the Elements are applied to the carrier layer in an equalized application flow applied. In a further step, they are on the carrier layer applied elements combined at least with a carrier layer.
- the inventive method opens up the possibility of a flat To produce structures that have an optically non-uniform surface of the Has wear layer, wherein the wear layer is rapportok.
- the optically inconsistent surface is due to the geometrically differing Elements achieved, the elements additionally different coloring could be.
- the absence of repetition of the wear layer is with regard to Mass production of a flat structure advantageous because according to the invention Process a reproducible producibility of a flat Formed is made possible.
- the geometrically different shape elements preferably according to at least one predetermined ratio introduced into the applicator. These items are regarding equalized their distribution in the applicator so that an im essential repeat-free wear layer can be produced.
- the elements in at least a portion of an exit of the applicator to the Application current are compressed.
- the elements that form the wear layer are preferably on the carrier layer laid, scattered and / or blown.
- the process of applying the elements Combinations of the individual types of application can also be applied to the carrier layer include.
- the elements can also be applied one after the other, where, for example, some of the elements are initially on the carrier layer placed and then further elements on the carrier layer with the placed elements are scattered.
- the elements by dividing a Primary material is formed.
- the elements can be confetti-like elements be designated.
- the elements are preferably made from the primary material punched out or formed by cutting the primary material.
- the primary material is preferably in the form of a strip or web. Under a ribbon-shaped Primary materials are also to be understood as those that are not necessarily have a rectangular cross section.
- the cross section of the band-shaped material can also be circular. More polygonal Cross sections of the band-shaped material are possible.
- the ribbon-shaped material is a hexagonal or octagonal Have cross-section.
- the primary material can be divided into at least two consecutive ones Splitting stations take place.
- the dividing stations can be corresponding Have cutting devices, in particular rotary cutting devices.
- the elements made by disassembling the sheet material have a substantially rectangular cross section. Should others Cross sections can be achieved by at an angle to each other arranged cutting edges of the cutters can be achieved. The same can also be achieved by forming punching tools.
- the Punching tools can have a honeycomb structure, for example. Stamping tools can also be used to create elements with a circular shape Cross section can be produced.
- the primary material or the elements have or have a thickness of 3 to 10 mm.
- the primary material is preferably a nonwoven fabric, in particular a needle felt, which is produced according to the manufacturing processes known per se for producing a needle felt. It is proposed that the primary material have a basis weight between 200 and 1000 gr / m 2 .
- the elements and / or the primary material is formed by yarns and / or threads.
- the elements are are preferably spinning products with different dimensions, Have structures and / or colorations.
- Some of the elements are preferably rovings, especially matched matches.
- the roving used as elements for the Formation of the wear layer are proposed, preferably have a Thickness from about Nm 0.5 to Nm 4.0 (about 2000 to 250 tex).
- carded yarns can also be used as elements for the design the wear layer are applied to the carrier layer.
- the carded yarn preferably have a thickness between about 0.5 and 5.0 Nm (about 2000 up to 200 tex).
- the elements are made from carded yarn is formed.
- the carded yarn threads preferably have a thickness between about 0.5 / 3 to 5.0 / 3 Nm (about 6000 to 600 tex).
- the surface structure, the wear layer is also preferred formed by half-comb yarns and / or half-comb threads.
- the half-worsted yarns preferably have a thickness between approximately 2.0 and 8.0 Nm (about 500 to 125 tex).
- the half-comb threads preferably have a thickness between about 2/2 and 8/2 Nm (about 1000 tex and 250 tex).
- the visual and structural appearance of the wear layer can also be changed are influenced that at least a part of the elements by textile parts, in particular pieces of fabric, nonwovens, is formed.
- Elements of the wear layer are made of a nonwoven that is special resilient and suitable for the property, i.e. in offices, hotels, restaurants, bars, Hobby rooms, sports halls, etc., can be used.
- the elements consist of natural and / or synthetic materials.
- the coloring of the wear layer can be due to the elements used to be influenced.
- the elements used to be influenced For example, it is possible to print or color Yarns, especially BCF yarns.
- the optical and the Structural as well as the haptic impression of a wear layer is also through influences the dimensioning of the elements. It is therefore according to the invention suggested that the elements be applied to the backing layer be crushed accordingly.
- the elements preferably have a length of about 20 to 120 mm.
- the union of the elements forming the wear layer with the carrier layer is preferably done by needling. According to another advantageous Thoughts are suggested that those forming the wear layer Elements are applied to an unconsolidated carrier layer. While the needling of the elements forming the wear layer can also unconsolidated carrier layer is solidified by needling. Through this The process variant is on the one hand the wear layer with the carrier layer unites and on the other hand solidifies the carrier layer itself, which simplifies Production of the flat structure is achieved.
- the Non-woven fabric in an additional process step using chemical binders is solidified.
- the Carrier layer on a surface opposite the wear layer is provided at least one further layer.
- the at least one further layer serves for product stability, fire resistance, conductivity or the like.
- the further layer can, for example be a spunbonded non-woven backing made of polypropylene with flame retardant.
